The Chicago Tribune has an article about a robot driven by a cockroach!. This cybug robot is about knee high with a hissing cockroach velcroed on top. The cockroach drives the robot by rolling a trackball. When it gets near a wall, LEDs shine in the roach's eyes so it will back away (roaches avoid bright light). The roach coach is a project of Garnet Hertz, a graduate student at the University of California, Irvine to test bug navigation intelligence. Mr. Hertz says that some roaches like to sit around for minutes on end, while others ignore the lights and like to bump into the wall on purpose. I'd bet mom's everywhere would jump when they see this thing coming!
